Thermal mass

Hi Chris,
This old thread on CN suggests 12” D or bigger best for tall pier in terms of deflection reduction https://www.cloudynights.com/article...amentals-r1236
They do not consider thermal issues. Like all these pier parameters, I guess it’s a compromise. I wonder how different cool down times would be to a smaller D pipe in terms of hours?

Cheers, Chris
